I own 8 talking books. They were full length audio books sold to the general public in the late 50s-60s. There is no specific information about the recording curve, however it must be RIAA which was the standard American recording curve at the time.
A demo record states that the 16RPM discs can be played on equipment at 33 1/3RPM with an adapter. Inference is that the recording curve was RIAA

The only 16-2/3 rpm record I ever had was when I was a child and I
received a phonograph as a birthday present and it had that speed and my
parents bought a Vox 12-inch LongLong Play record entitled "Around The
World Around The Clock" which had easy listening instrumental music from
differing countries (like "La Vie en Rose"). As far as I recall, it was
pressed the same as a standard LP - size, centre hole, etc. It went away
in a purge, I suspect, after I got my Dual 1219 which wouldn't play it.
